BACKGROUND

A warm-air comb is a comb with an air blowing function, which can dry and set hair when combing the same. The existing combs generally comprise a housing, a heating element, comb teeth, a vane and a motor, wherein a plurality of air outlets are formed in the circumference of the housing; the comb teeth are uniformly distributed on the circumference of the housing; the heating element, the vane and the motor are installed inside the housing; the motor is used for driving the vane to rotate and bring external air into the housing; and the air is discharged via the air outlets after being heated by the heating element.

In the case of the existing warm-air combs, the outgoing air is not concentrated, the air volume is relatively small and the air speed is relatively low. Moreover, the heating effect is poor and the outgoing air is not uniform in temperature.

SUMMARY

In view of the shortcomings in the prior art, the object of the present invention is to provide a warm-air comb, which may provide concentrated outgoing air, large air volume, high air speed, good heating effect and relatively uniform outgoing air temperature.

To achieve the above object, the following technical solution may be adopted:

A warm-air comb may include a housing and an air guiding mechanism, wherein an air inlet is formed in one end of the housing; the air guiding mechanism is arranged inside the housing and is used for bringing external air into the housing via the air inlet. The warm-air comb may also include a thermal insulation cylinder, a heating element and an air combing head, where the thermal insulation cylinder is arranged inside the housing, a cylinder opening of the thermal insulation cylinder faces toward the air inlet, and the outer edge of the cylinder opening is attached to the inner wall of the housing. An opening may be formed in the lower portion of one end of the thermal insulation cylinder away from the cylinder opening, and an inner diameter of the thermal insulation cylinder may gradually decrease from the cylinder opening to the opening. The heating element may be arranged inside the thermal insulation cylinder. An air discharge position may be provided on the housing below the opening, and a plurality of air outlets may be formed in the air discharge position. The air combing head may include a base installed on the housing and comb teeth fixedly arranged on the base, where a plurality of air holes communicated with the air outlets one by one are formed in the base.

The air guiding mechanism may be located between the air inlet and the cylinder opening, and the air guiding mechanism may include a motor and a vane driven by the motor.

A clamping hole may be formed in the base. The warm-air comb may further include a sliding element and an elastic resetting element. A clamping tongue may be arranged at one end of the sliding element close to the base; a shifting part may be arranged at the lower end of the sliding element; the sliding element may be slidably installed on the housing, and the shifting part may be exposed outside the housing. The shifting part may be used for being shifted to drive the sliding element to move between a position where the clamping tongue is clamped in the clamping hole and a position where the clamping tongue is located outside the clamping hole; and the elastic resetting element may be used for providing an elastic resetting force for the sliding element to approach the air combing head.

The heating element may be a quartz tube.

Embodiments according to the present disclosure may have the following beneficial effects:

When a warm-air comb according to embodiments of the present disclosure is at work, the air guiding mechanism may bring external air into the housing via the air inlet. The external air may then enter the thermal insulation cylinder via the cylinder opening to be heated by the heating element. Meanwhile the air may be gradually compressed with the gradual decrease of the inner diameter of the thermal insulation cylinder and is passed to the air discharge position via the opening at a relatively high air speed. Then, a portion of the air may be discharged via the air outlets and the air holes. In this way, the outgoing air may be relatively concentrated, and the air speed may be relatively high and the air volume may be relatively large. Moreover, since the air holes are small, a portion of the air incapable of passing through the air holes may be blocked by the inner wall of the housing, return into the thermal insulation cylinder, and mixed with new air, which may be heated together with the same. In this way, the heating effect is better, and the mixed air is more uniform in temperature when compared with previous combs.

When the warm-air comb is at work, the air guiding mechanism 20 brings external air into the housing 10 via the air inlet 11, the external air enters the thermal insulation cylinder 30 via the cylinder opening 31 to be heated by the heating element, meanwhile the air is gradually compressed with the gradual decrease of the inner diameter of the thermal insulation cylinder 30 and is passed to the air discharge position 12 via the opening 32 at a relatively high air speed, a portion of the air is discharged via the air outlets 121 and the air holes 411, in this way, the outgoing air is relatively concentrated, and the air speed is relatively high and the air volume is relatively large; moreover, since the air holes 411 are small, a portion of the air incapable of passing through the air holes 411 is blocked by the inner wall of the housing 10, returns into the thermal insulation cylinder 30, and is mixed with new air and is heated together with the same, in this way, the heating effect is better, and the mixed air is more uniform in temperature.

Further, the air guiding mechanism 20 is located between the air inlet 11 and the cylinder opening 31, and the air guiding mechanism 20 comprises a motor 21 and a vane 22 driven by the motor 21. The air guiding mechanism 20 can also be other mechanisms, as long as the external air can be introduced into the housing 10 at a certain speed.

Further, a clamping hole 413 is formed in the base 41; the warm-air comb further comprises a sliding element 50 and an elastic resetting element 60; a clamping tongue 51 is arranged at one end of the sliding element 50 close to the base 41; a shifting part 52 is arranged at the lower end of the sliding element 50; the sliding element 50 is slidably installed on the housing 10, and the shifting part 52 is exposed outside the housing 10; the shifting part 52 is used for being shifted to drive the sliding element 50 to move between a position where the clamping tongue 51 is clamped in the clamping hole 413 and a position where the clamping tongue 51 is located outside the clamping hole 413; and the elastic resetting element 60 is used for providing an elastic resetting force for the sliding element 50 to approach the air combing head 40, so that when the shifting part 52 is not shifted, the clamping tongue 51 can be clamped in the clamping hole 413. In this way, after the air comb is installed, the clamping tongue 51 can be clamped in the clamping hole 413 to fix the air combing head 40, and for disassembly, it only needs to shift the shifting part 52 so that the clamping tongue 51 is removed from the clamping hole 413, so as to detach the air combing head 40 for cleaning (as shown in FIGS. 6 and 7).
